Alloy Q310NQL2 atmospheric corrosion resistant structural steel steel BBN good property

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they Q310NQL2 atmospheric corrosion resistant structural steel work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.

In the production process of the ironmaking process, the moisture content and air temperature of the ironmaking blast furnace blast have a direct impact on the fuel consumption and fuel consumption structure of the ironmaking process. Blast furnace blast dehumidification is to remove the moisture in the blast furnace blast, eliminate the adverse effects of atmospheric humidity fluctuations on the blast furnace forward movement, and create stable operating conditions for the fans.
